Ahh, I remember writing those from a very lonely, dark room in Garching...  :)

What's ldd /home/astro/jwise/local/lib/python2.6/site-packages/mpi4py/MPI.so
report?  And can you try running with the python2.6-mpi executable,
see if that helps?

This is a bit new to me, as well...  maybe it's turning down some
library loads because of conflicts?  What happens if you set LD_DEBUG
(maybe to 'files' or 'bindings' -- but 'help' should clear up what's
available.)

Best,
